Smoke damper type: a normally open normally closed smoke damper smoke damper 2. 3. Remote control type smoke damper (rope control type) 4. Automatic reset type smoke damper 2.1 Chang open type smoke damper functions as follows: 2.1.1 usually was normally open state, when the fire occurred after the control center by DC24V power output, the valve automatically closes 2.1.2 when the pipe when the temperature reaches 280 ℃ htfc Fire cabinet centrifugal wind. chassis, fuse action, the valve automatically closes. 2.1.3 Output signal the valve is closed, interlocking exhaust fan stops. 2.1.4 manually shut down, manually open 2.2 normally closed smoke damper, smoke, also known as secondary action damper functions are as follows: 2.2.1 usually was normally closed when the fire broke out, by the control center DC24V power input, the valve quickly open the valve opening signal output 2.2.2, 2.2.3 interlock control fire exhaust fan is turned on manually. manual reset closed. 2.2.4 When the pipe temperature reaches 280 ℃, fuse action, the valve is closed again. 2.3 remote-controlled smoke damper (rope-controlled) exhaust valve is a subsidiary unit belonging to the building. Price dampers, smoke machine when the utility model is to solve the current common when using a common flue damper, smoke machine smoke is not smooth problems and provide a common way to use a common exhaust smoke exhaust smooth valve. The utility model comprises a housing (3) round damper manufacturers, their structure points are on one side of the housing (3) having a smoke machine can be connected to the exhaust pipe (1) of the pipe (2), housing (3) provided with moving flats (9), the wind pipe towards the upper (10) on the active axis inclination direction of the other side of the flange duct (7) (6) on the upper (11) centrifugal wind chassis, housing (3) disposed within the body having a filter (12) of the net bracket (5).
